Erica Remkus chose the wrong patch of Hamptons beach to relieve herself. As the 36-year-old woman squatted down on a section of sand in exclusive Sag Harbor Cove Saturday night, she heard a woman scream: “What are you doing?!”

The woman yelled some more: “You can’t pee in front of my house! You have to go away. You’re standing on my rocks. You can’t pee on my rocks. I walk there!”

It turned out that the screaming woman was former supermodel Christie Brinkley, Remkus told the New York Post.

However, Remkus didn’t recognize Brinkley at first, and she argued back that she was on public property.

“These are not your rocks,” Remkus, a hairdresser, said she told the woman.

Remkus claims she was standing on a section of sand that was deserted, except for a man who himself had just urinated there.

“This is not your beach,” Remkus said she shouted back some more. “The beach is public property. You don’t own it.”

Brinkley ended the argument by pulling out a hose and blasting Remkus from about 30 feet away, according to police.

It was then that Remkus realized that the woman hosing her down was the former Sports Illustrated cover girl.

But still defiant, Remkus found another patch of sand, where she promptly relieved herself.

In turn, Brinkley recorded the act of public urination on her cell phone, then called the police.

The police responded and interviewed Remkus but declined to cite her, with authorities saying they usually don’t press charges unless officers themselves witness the urination.

For her part, Remkus said she wouldn’t have continued the dispute if Brinkley hadn’t used the hose on her.

“I would not have peed if she didn’t spray me,” Remkus said. “After that, I kind of had to.”
